Yahya related to me from Malik from Zayd ibn Aslam from a man of the Bani'd-Dil called Busr ibn Mihjan from his father Mihjan that he was in a gathering with the Messenger of Allah ﷺ and the call to prayer was made. The Messenger of Allah ﷺ rose and prayed and then returned. Mihjan remained sitting and did not pray with him. The Messenger of Allah ﷺ said, "What prevented you from praying with the people? Aren't you a muslim?" He said, "Of course, Messenger of Allah, but I have already prayed with my family." The Messenger of Allah ﷺ said, "When you come, pray with the people, even if you have prayed already."
أَنَّهُ كَانَ فِي مَجْلِسٍ مَعَ رَسُولِ اللَّهِ ﷺ فَأُذِّنَ بِالصَّلاَةِ فَقَامَ رَسُولُ اللَّهِ ﷺ فَصَلَّى ثُمَّ رَجَعَ وَمِحْجَنٌ فِي مَجْلِسِهِ لَمْ يُصَلِّ مَعَهُ فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ مَا مَنَعَكَ أَنْ تُصَلِّيَ مَعَ النَّاسِ أَلَسْتَ بِرَجُلٍ مُسْلِمٍ فَقَالَ بَلَى يَا رَسُولَ اللَّهِ وَلَكِنِّي قَدْ صَلَّيْتُ فِي أَهْلِي فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ إِذَا جِئْتَ فَصَلِّ مَعَ النَّاسِ وَإِنْ كُنْتَ قَدْ صَلَّيْتَ
